[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined filtering compensation module, including a protective box. Several input interfaces are provided on one outer wall of the upper end of the protective box, and several output interfaces are provided on the other outer wall of the upper end of the protective box. An integrated control unit is located at the center of the bottom of the protective box. A filtering unit is located on the bottom of the protective box on one side of the integrated control unit, and a dynamic reactive power compensation unit is located on the bottom of the protective box on the side of the integrated control unit away from the filtering unit. An air inlet is provided on one outer wall of the lower end of the protective box, with one end extending into the interior of the protective box.

[0006] Preferably, positioning seats are provided on both outer walls of the bottom of the protective box, and two semi-waist-shaped holes are provided on the outer walls of the positioning seats. The semi-waist-shaped holes are provided so that the protective box can be bolted and installed using bolts.
[0007] Preferably, a first sliding frame is fixed on the outer wall of the protective box on both sides of the air inlet, and a first metal baffle is slidably installed on the upper inner wall between the first sliding frames. The first metal baffle is used to open and close the air inlet.
[0008] Preferably, a first upper magnetic strip is provided on the outer wall of the protective box above the first sliding frame, and the bottom end of the first upper magnetic strip is attracted to the top end of the first metal baffle. A first lower magnetic strip is provided on the outer wall of the protective box below the first sliding frame.

[0010] Preferably, a second upper magnetic strip is provided on the outer wall of the protective box above the second sliding frame, and the bottom end of the second upper magnetic strip is attracted to the top end of the second metal baffle. A second lower magnetic strip is provided on the outer wall of the protective box below the second sliding frame. The second upper magnetic strip and the second lower magnetic strip are provided to allow the second metal baffle to be attached to the protective box.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the combined filter compensation module not only extends the service life of the filter compensation module, but also improves the convenience of using the filter compensation module, and ensures the stability of the filter compensation module during use.
[0012] (1) By integrating the filter unit, dynamic reactive power compensation unit and integrated control unit inside the protective box, and symmetrically setting air inlets and outlets on the outer walls on both sides of the protective box, the protective box can block and protect the filter unit, dynamic reactive power compensation unit and integrated control unit, and the symmetrically set air inlets and outlets can ventilate and dissipate heat for the components inside the protective box, thereby reducing the corrosion of the components inside the protective box by external factors and reducing the burning of the components inside the protective box due to high temperature, thus extending the service life of the filter compensation module.

When the first metal baffle moves up and is attracted to the first upper magnetic strip, the air inlet can be opened and closed. When the first metal baffle moves down and is attracted to the first lower magnetic strip, the air inlet can be blocked and closed. Then, by pulling the second metal baffle up and down, the second metal baffle is moved inside the second sliding frame. When the second metal baffle moves up and down and is attracted to the second upper magnetic strip or the second lower magnetic strip, the air outlet can be opened and closed. Thus, the air inlet and outlet can be opened and closed for ventilation and heat dissipation when the filter compensation module is in use, and the air inlet and outlet can be closed to prevent dust when the filter compensation module is not in use, thereby improving the convenience of using the filter compensation module.
[0014] (3) By using bolts to pass through the semi-circular hole and screw them into the threaded hole reserved on the installation platform, the protective box can be bolted and positioned by the positioning seat, which can effectively reduce the displacement of the filter compensation module caused by external force factors, thereby ensuring the stability of the filter compensation module during use.

The protective box 1 has positioning seats 2 on both outer walls of its bottom, and the positioning seats 2 have two semi-waist-shaped holes 201 on their outer walls.
[0022] In use, the semi-waist-shaped hole 201 is provided so that the protective box 1 can be bolted and installed using bolts;
[0023] Several input interfaces 8 are provided on one side of the upper outer wall of the protective box 1, and several output interfaces 9 are provided on the other side of the upper outer wall of the protective box 1. An integrated control unit 12 is provided at the center of the bottom of the protective box 1. A filter unit 10 is provided on the bottom of the protective box 1 on one side of the integrated control unit 12. A dynamic reactive power compensation unit 11 is provided on the bottom of the protective box 1 on the side of the integrated control unit 12 away from the filter unit 10. An air inlet 3 is provided on one side of the lower outer wall of the protective box 1. One end of the air inlet 3 extends into the interior of the protective box 1. First sliding frames 4 are fixed on the outer walls of the protective box 1 on both sides of the air inlet 3. A first metal baffle 5 is slidably installed on the upper inner wall between the first sliding frames 4.
[0024] In use, the first metal baffle 5 is set to open and close the air inlet 3.
[0025] The outer wall of the protective box 1 above the first sliding frame 4 is provided with a first upper magnetic strip 6, the bottom end of the first upper magnetic strip 6 is attracted to the top end of the first metal baffle 5, and the outer wall of the protective box 1 below the first sliding frame 4 is provided with a first lower magnetic strip 7.
[0026] In use, the first upper magnetic strip 6 and the first lower magnetic strip 7 are set to allow the first metal baffle 5 to be attached to it.
[0027] An air outlet 13 is provided on the outer wall of the other side of the lower end of the protective box 1. One end of the air outlet 13 extends into the interior of the protective box 1. A second sliding frame 14 is fixed on the outer wall of the protective box 1 on both sides of the air outlet 13. A second metal baffle 15 is slidably installed on the upper inner wall between the second sliding frames 14.
[0028] In use, the second metal baffle 15 is used to open and close the air outlet 13.
[0029] The outer wall of the protective box 1 above the second sliding frame 14 is provided with a second upper magnetic strip 16, the bottom end of the second upper magnetic strip 16 is attracted to the top end of the second metal baffle 15, and the outer wall of the protective box 1 below the second sliding frame 14 is provided with a second lower magnetic strip 17.
[0030] In use, the second upper magnetic strip 16 and the second lower magnetic strip 17 are used to attach the second metal baffle 15 to the magnetic field.
[0031] In this embodiment, the protective box 1 is first bolted in place by passing a bolt through the semi-circular hole 201 and screwing it into the threaded hole reserved on the mounting platform. This reduces the displacement of the filter compensation module due to external forces. Then, the filter unit 10, dynamic reactive power compensation unit 11, and integrated control unit 12 are integrated inside the protective box 1. Air inlets 3 and outlets 13 are symmetrically arranged on the outer walls on both sides of the protective box 1. The protective box 1 provides protection and isolation for the filter unit 10, dynamic reactive power compensation unit 11, and integrated control unit 12, while the symmetrically arranged air inlets 3 and outlets 13 provide ventilation for the interior of the protective box 1. Ventilation and heat dissipation are provided for the components on both sides, thereby reducing the corrosion of the internal components of the protective box 1 by external factors and reducing the phenomenon of burning of the internal components of the protective box 1 due to high temperature. Finally, by pulling the first metal baffle 5 up and down, the first metal baffle 5 is slid inside the first sliding frame 4. When the first metal baffle 5 moves up and is attracted to the first upper magnetic strip 6, the air inlet 3 can be opened and closed. When the first metal baffle 5 moves down and is attracted to the first lower magnetic strip 7, the first metal baffle 5 can block and close the air inlet 3. Then, by pulling the second metal baffle 15 up and down, the second metal baffle 15 is slid inside the second sliding frame 14. When the second metal baffle 15 moves up and down and attaches to the second upper magnetic strip 16 or the second lower magnetic strip 17, it can open and close the air outlet 13. This allows for ventilation and heat dissipation when the filter compensation module is in use, and for dust prevention when the air inlet 3 and air outlet 13 are closed when the filter compensation module is not in use. Furthermore, the filter unit 10 adopts a combination of advanced passive and active filtering technologies, which can automatically identify and filter out various harmonics in the power grid, while reducing energy loss during the filtering process. Through built-in sensors and microprocessors, it can achieve real-time monitoring and analysis of the harmonic components of the power grid and dynamically adjust the filtering. The strategy involves a dynamic reactive power compensation unit 11 based on SVG technology, which can quickly respond to changes in the reactive power demand of the power grid, automatically switch capacitor banks or adjust the SVG output to achieve dynamic reactive power compensation, improve the power factor of the power grid, and reduce line losses. The integrated control unit 12 is responsible for coordinating the work of the filter unit 10 and the dynamic reactive power compensation unit 11, automatically adjusting the working mode according to the power grid status, and providing remote monitoring and fault diagnosis functions to facilitate remote management by operation and maintenance personnel. Since the filter unit 10, the dynamic reactive power compensation unit 11 and the integrated control unit 12 are all existing technologies, their detailed structures will not be described further, thus completing the use of the filter compensation module.
